STEAM-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent Ila 347,463, dated August 17, 1886.

Application tiled January 2, 1886. Serial No. 187,475. (No model.)

To all whom,- it may concern.-

I pipe, E E E", into the regulator XV, from which Be it known that I, ZACCUR PRALL BOYER,

it enters through part E* into the boiler A.

a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented a new and useful Improvement in a Combined Range and Steam-Heating Apparatus, of which the following is a specification.

My invention relates to an improvement in steam-heating apparatus,- and the objects of my invention are, first, to provide a simple and economical apparatus for the heating of a building or buildings by steam generated by means of a tubular boiler, combined with a stove,

range, or other heating or cookingapparatus, so as to utilize the waste heat from said stove or range; second,'to economize in the use of fuel in heating a building by steam; third, to

do away with the necessity of a furnace inthe cellar of a building, or of any heating, appli- These hot and cold water connections between boiler A and the water-backs B B B may be so placedor arranged as shall make the most suitable and desirable connections for the purposes of conveying the cooler water into the Water-backs, and from thence the hot water into the boiler.

G is a pipe to convey the steam generated in the boiler to the coils or radiators throughout the building.

H is a pipe to return to the boiler the steamcondensatiou resulting from changes in the temperature along the line of the pipes, coils, or radiators.

B B B are water-backs surrounding the fire-box, on three sides of the same, in separate sections or parts, as shown in Fig. 4. These water-backs may be of any shape or form, according to the form of the fire-box and to the quantity of water desired to be heated.

O is a short smoke, gas, or draft stack leading into the chimney of the building.

D is a water-feed pipe passing lengthwise through boiler A at D, as shown in Fig. 2, connected at Y with part D, which in turn is connected to water-back Bat D part D" connected to water-back B at D, and part D connected to water-back B at D.

E is a water-pipe to convey Water from water-backs at U U U through parts of same tering the boiler-tubes direct, and to send said current around the ovens.

The fire-box K is shown in Fig. 4 as a parallelogram; but it may be constructed in form square, circular, or otherwise, as desired. Boiler A need not be placed just in the rear of the fire-box. It may be placed on either side or at any angle with the firebox, as the location of the place wherein the apparatus is to be set may require.

The operation of my invention is as follows: The water enters the boiler at D through main feed-pipe D, which passes through steam and water-space of the boiler lengthwise and ex tends below the lower end of the boiler, where, at Y, it passes through parts D and D of feedpipe D, entering the water-backs B at D and B at D. From part of feed-pipe D extends D", which has a connection with water-back B at D. After being heated the water in the waterbacks passes out through pipe E at U, E" at at U*, and E at U" into main pipe E, through which the water passes into the inlet end of the watcrlevel regulator \V, and, passing out through pipe E, is discharged into the boiler A. The heated aineurrent from the fire-box rises, and if the dampers Q Q are open, as shown in Figs. 2 and 3, passes up and around the ovens and under boiler A and up the hotair fines, as R R It. If said dampers be closed and damper or plate Z open, the hot air passes directly under the boiler and up the hot-air fines, as R R R, thus presenting a large heating-surface, and, owing to the supply-pipe D passing through the steam and hot temperature of the upper part of the boiler A, the supply-water is gradually heated from its introduction into the boiler, and the temperature of the water is high before it enters the waterbaek. To introduce cold water into a waterback of a stove in which there is a fire would be attended with some degree of danger. It is readily seen that, owing to the position of the feed'pipe D in the boiler in such close proximity to the heat-tnbes, the water in the feedpipe receives additional heat therefrom before it reaches the water backs. After leaving the regulator and entering the boiler the water is near to the vaporizing-point, and when inside the boiler is converted into steam by the heat circulating through the heat ilues l. The steam then collects at the upper part of the boiler and passes out through steam-pipe G, to be distributed to any point desired by any of the well-known means. The condensation of the steam, caused by the difference in the temperature along the line of the distribution appliances, is carried back to the boiler by means of returning-pipe H. The regulator maintains the water in the boiler at an even height by means of an ordinary automatic float-valvc or other appliance suitable for the purpose. To the regulator is adjusted the proper connections for a gageindicating the exact height of the water in the boiler.

\Vhen the pressure of the steam on theboiler becomes too great, it is relieved by the open- The surplus steam ing of the safety- "alve N.

is thus enabled to escape into the smokestack G.

Of course, it is understood that the stove or range can be used for any and all domestic purposes for which they are at present adapted, and it is also evident that the stoves, ranges, or other heating appliances now in use may be altered or changed so as to meet the requirements of adjustment with my invention without necessitating the construction of new ranges or stoves.

It is of course understood that the hot water needed for ordinary kitchen and bath-room purposes is derived from the steam-boiler. It will be obvious that the foregoing invention greatly reduces the cost of heating the houses, where it is customary to have independent apparatus for that purpose, by entirely dispensing with the ordinary furnace, and by a saving of from fifty to seventy-five per cent. in the amount of fuel required for purely heating purposes. A great drawback to the employment of heating-furnaces as at present practiced is the inconvenience arising from the heating of the cellars in which they are genorally placed. This is entirely obviated by my invention.

Il'aving sufficiently described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a combined range and steam-heating apparatus, a water-back, with a boiler having tubes, pipes connecting water backs and boiler, and a feed-pipe passing through said boiler and connecting with a water-back.

2. In a combined range and steam-heating apparatus, a wate1-bacl ,with a boiler having heat-tubes, pipes connecting the water-backs and boiler, and a feed-pipe passing through said boiler in close proximity to the heattubes.

3. In a combined range and steam-heating apparatus, a fire-box, a plate above the firebox, dampers Q Q, a flue between the plate and fire-box, ovens at either side and above the lire-box, and ilues leading around said ovens communicating with the exit-flue.
